A classical planet is an astronomical object that is visible to the naked eye and moves across the sky and its backdrop of fixed stars, appearing as wandering stars. Visible to humans on Earth there are seven classical planets. They are from brightest to dimmest: the Sun, the Moon, Venus, Jupiter, Mercury, Mars and Saturn.
